Enzyme present in saliva is

• A) Maltase
• B) Ptyalin
• C) Sucrase
• D) Invertase

The enzyme present in saliva is known as ptyalin, which is also referred to as salivary amylase. This enzyme plays a crucial role in the digestion of carbohydrates by breaking down starches into simpler sugars.

Other Enzymes Mentioned

• Maltase: This enzyme is responsible for breaking down maltose into glucose, but it is not found in saliva.
• Sucrase: This enzyme helps in the digestion of sucrose, but it is primarily active in the small intestine.
• Invertase: This enzyme converts sucrose into glucose and fructose, but it is not present in saliva.

In summary, the correct answer is B) Ptyalin.
